토목기술이란 토목사업을 지탱하는 기술로서 여기서 토목기술이란 토목을 주로 하여 건축구조의 공학적인 것을 포함한 기술이라고 할 수 있다. 토목사업은 오늘날 국토의 보전ㆍ수자원개발ㆍ교통로정비(항만포함)ㆍ도시와 지방계획 및 상하수도를 포함한 도시건설 등이며, 어느 것이나 국민의 생산과 생활환경개선 등 우리 인간의 앙적한 생활과 복지편익을 추진시키는 기간산업이 아닌 것이 없다. 그래서, 인간사회가 발전을 갈망한다면 토목건설사업이 선행되어야하고, 토목사업으로 확립된 기반아래 국민들의 건전한 생활이 영위되는 것은 물론이다. 토목이라하면 주로 우리나라에서는 국토건설로서 지역, 또는 국가사회의 경제발전에 크게 영향을 미치는 토목건설사업을 말한다. 이것은 토목기술의 발전이 그때 그때의 건설사업으로서 구상화되는 까닭이라 하겠다. 한편, 인간의 가치관에 변화가 생기고 자원문제ㆍ공공문제ㆍ생활환경문제 등이 크게 변화하는 단계에 있어서도 그 방향을 탐색하고 우리 인간 및 국가사회가 의도하는 건설공간구상을 계획하고 사업화 하는데 매우 중요한 것은 토목건설인 까닭에서이다. 이런 의미에서 최근 100년간의 경이적인 서구의 근대화 과정에서의 토목기술 발전, 즉 이 기술이 매우 오늘날 세계를 변혁시킨 사실에서 출발한데 대비하여 우리 나라 개항 100년 이후의 안타까운 우리의 기술수용과정을 볼 때 1986년 강화도조약 이후 한반도는 일본 및 청국을 위시한 구미열강외세의 각축장으로서 혼미된 서구근대기술의 도입요람기로 시작하여 1810년 한일합방에서 8.15해방까지 일본통치하에서 타율적인 토목ㆍ건축기술의 도입으로 한마디로 말해서, 거의 70년간의 진통기가 있음을 엿볼 수 있다. 하지만 최근 30년 사이에 그야말로 우리 토목기술터전은 급격하게 성장 발전하고 있다.

지난 2008년부터 2013년까지 우리나라는 홍수방어 및 가뭄을 대비하기 위하여 하천정비사업인 4대강 사업을 실시하였다. 또한, 4대강 사업은 환경적인 측면을 고려하기 위해 하천변에 대체습지를 조성하였다. 하지만, 대체습지 조성 이후 대체습지에 대한 평가가 제대로 이루어지지 않아 관리하는데 있어 문제가 발생하고 있다. 따라서 대체습지에 대해 기능을 평가하고 평가 결과를 통해 관리방안을 수립하는 것이 필요하다. 현재 습지의 기능은 수문학적, 생태학적, 지형학적으로 구분하여 평가하고 있다. 본 연구에서는 대체습지의 수문학적 평가를 위해 필요한 대체습지 제원 및 수리수문요소 등 관련자료를 수집하였다. 빈도해석과 수문모형을 통해 침수빈도, 침수심 등을 분석하여 수문학적 측면으로 대체습지를 평가하였다. 본 연구의 결과는 4대강 사업으로 조성된 대체습지의 관리방안을 수립하는데 기초자료로 활용될 것으로 기대된다.

In case of low benefit project with low traffic or high-priced project, existing analysis of cost and benefit tends to present a low feasibility. However, considering the improvement of environment, intensification of disaster prevention, public stability of countryside area and formation of good scenery, these projects can have a feasibility. This paper analyzes and summarizes the indirect benefit of some ripple effects, caused by road projects, and presents the methodology and process in order to change the indirect benefit into monetary value.

Over the past years, complex project which has the object to accomplish housing complex, commercial complex etc, recently is changing to multi-complex projects because of development in IT sector. Improvement in the quality of life, life pattern has been and is being changed, these modernized and improved version of life brings the concept of U-city. Department of urban planning and engineering, civil engineering and architecture engineering in every university educate students according to the changing world in order to handle these complex projects in real world. In most cases department of urban planning and engineering teach project planning and department of civil and architecture engineering teach project design and construction. In most of the projects planning followed by design and construction need to be accomplished, but current observation in the present curriculum shows that it is difficult to expect the continuity. The present curriculum of civil engineering has to change as complex projects deal with various different structures during the design and construction phase of these projects. This study examined curriculums from the department of urban and civil engineering related to structural design and construction and survey importance of design works which overlap urban and civil engineering targeted on design engineers. After understanding design works and results obtained from survey we propose for an advanced efficiency method.

This study investigated checked risk level before bid, actual risk level after award, contingency, and cost growth rate in the 124 international construction projects executed by Korean major companies. This study conducted comparative analysis by product type using rank analysis, ANOVA and correlation analysis. As a result, plant and civil projects have worse risk level than architecture projects not only in before bid but also in after award. Especially, country risk is the worst risk in both plant and civil projects, followed by project risk and capability risk. Also, although plant and civil projects reflect more contingency than architecture projects, contingency is not correlated with the checked risk level before bid. Lastly, the cost growth rate is correlated with the actual risk level in all product types. This study is expected to support in planning better practical risk management for international construction projects.

As the national competitive power indicator, the infrastructures have been constructed with government's SOC budgets. However, even SOC budget is decreased, Public-Private Partnership Project (PPP project) has been introduced to solve demands on extending infrastructures, and among PPP projects, road projects take high portions. This study analyzes the operation & management item of financial model which is connected to the O&M cost and project proposal of previously proposed road project and analyzes the Korea Expressway Co.,'s project cost items and O&M tasks to reflect the characteristics of road projects. Based on results, this study suggests necessity of the O&M cost breakdown structure and the cost calculation standard on each cost item. Also, for the existing task execution tools, O&M cost calculation tool and finance analysis task tool will be integrated, and the system is suggested web-based system. Thus, it is expected that it contributes to the securing overall business values on PPP project and expending profit-base infrastructures.

With rapid industrialization since the 1960s, development projects have contributed to the development of the national economy. In addition to the development projects promoted by the government, private project operators are also promoting development projects for reasons such as increased public convenience, insufficient financing of SOC assets, and expansion of their own development projects other than public orders. However, as the economy has been stagnating due to several factors such as continued supply of facilities for decades and recent COVID-19, the success of the development projects are unsure these days. Therefore, this study attempted to analyze project costs through the case of such development projects, and to present a plan to judge and manage the risks of each project cost item in advance. The AHP technique, which is widely used as a risk factor selection method for existing development projects, was used, and items were determined through interviews with experts related to development projects in order to stratify the upper and lower subjects of the risk. We analyzed how the derived risk factors affect the business performance through sensitivity analysis, and finally substituted the risk factors management plan into the risk response strategy and suggested.
